The Glow-worm 0020136540/SD Domestic Hot Water (DHW) Heat Exchanger is a genuine replacement plate heat exchanger designed to restore efficient hot water performance in Glow-worm Betacom boilers. This component transfers heat from the primary circuit to the domestic hot water supply, ensuring strong flow rates and consistent temperature.

Over time, DHW heat exchangers can become blocked with scale, debris, or sludge, leading to reduced hot water output, fluctuating temperatures, or slow hot water delivery. Replacing it with this genuine Glow-worm part restores full efficiency and reliable hot water performance.
